Specification of Letters Patent. Patented NOV. 18 Ililljlg,

Application filed October 14, 1918. Serial No. 258,058.

To all whom it may concern:

Be it known that I, OLIVER J. a citizen of the United States, residing at Burlingame, in the county of San Mateo and State of California, have invented certain new and useful Improvements in Crushers, of which the following is a speci-' thereof will be hereinafter described and claimed.

ley and flywheel fan,

In the manufacture of crushers and like machines comprising a suitable casing and arotor having pivoted hammers, the hammer rods forming the pivot for the hammers, pass through disks mounted on a shaft and alternating with the hammers. A flywheel and pulley on opposite ends of the shaft outside the bearings interfere with the removal of the hammer rods, when the rotor is longer than the space intervening between the flywheel and pulley respectively, and the adjacent end of the rotor when the cover of the casing is raised either the re moval of flywheel or pulley is necessary or some other means must be provided, to allow of taking out the rods in such a case. Frequent change ofhammers for redressing the points or for replacement, calls for means to facilitate withdrawing said hammer rods,-

which I will now describe in connection with the accompanying drawing on which like reference letters indicate corresponding parts, and in which Figure 1 represents a perspective view of a rotary shaft, with pulon the outer ends, and a rotor in the middle embodying my invention; Fig. 2, a longitudinal section of part of a suitable casing and a rotor similar to that shown in Fig. 1 mounted therein; and i Fig. 3, an end view of such a rotor.

The letter A designates a suitable casing, with a cover B adapted to be lifted as indi- WILLIAMS,

each rod, and means cated by dotted lines from a rotary shaft C, mounted in suitable bearings D, and having at one end a pulley E, and. at the other end a flywheel F that may carry a fan G as in Fig. 1. On said shaft and within the casing, are mounted a set of disks H, carrying alternating pivoted hammers I by means of hammer rods in sections J that pass through registering openings in said disks and hammers, and meet at the central or other intermediate disk H. This re. section J is shown flush with'the outside of the end disk, and a plate ring K is fastened by capscrews L, or otherwise, detachably to the outer face of said end disk, to serve as a keeper to prevent. said rod J from shifting in said disks. A hole 70 Fig. 3 in said plate is adapted, by rotating the plate, to register successively with the hammer rods, to allow of their withdrawal when hammers are to be renewed and a tapped hole M in the outer end of rod J, allows of screwing in the end of a bolt for pulling out said rod.

Fig. 2 shows-in dashed lines, a section of.

lengths of section as corless than, said intercomprising a shaft, a set of disks having.

registering holes, and hammer rods mounted in said holes, a cover plate rotatably mounted on the outer face of the set of disks and normally covering the ends of said rods and having a hole adapted to register successively'with' said rods by rotated adjustment of said plate to allow withdrawal of to secure the plate in its normal closing position, and allow of rotating it to register said hole with said rods successively when it is desired to withdraw said rods; substantially as described.

In testimony whereof I have affixed my signature.

OLIVER J. WILLIAMS.
